FMplus is a patent-pending system developed in Switzerland that allows cable operators to introduce fast internet, but at the same time does not require that FM (via cable connection) be switched off.
The DAB+cable adapter enables the reception of DAB+cable signals from the cable connection and converts them into frequencies that can be received with standard DAB+ devices.
In addition to energy, data is also transmitted via the low-voltage power grid. On the consumer side, PLC adapters are used to extend the Internet connection, e.g. from the living room to the cellar.
But the professionals also send data via the grid. Energy meters, for example, are thus read remotely and the new requirements for the “smart grid” demand more and more information about the network, which is also sent via the “power lines”. New energy sources (wind, solar …) make it more demanding to keep the grid stable. This requires much more undelayed data than before. Therefore it is always important that the grid remains “clean” and the data can flow undisturbed.
Unfortunately, there are more and more interfering signals on the network. These can be caused by non-conforming or damaged power supply units, motors, dimmers, power electronic components such as inverters or other devices that can affect data transmission over long distances.
Electricity utilities (EW) depend on data transmission running as smoothly as possible and therefore they invest a great deal of commitment in the quality of their grid areas. The HF sensor -1 – as a supplement to a power analyser – has proven very useful for detecting interference signals on the power grid. The sensor can detect the interfering signals wirelessly. It can be held along lines and immediately indicates where the interference is getting stronger or weaker.

More and more, FM and DAB receivers are used in the same household. By sharing these different receivers, the synchronization of the various vectors becomes undoubly important.
If two audio signals with a difference of more than 200ms hit the human ear, not only the hearing comfort but also the listener’s hearing will decrease massively. With the Delay Time Controller (DTC) and for example Eventide’s delay devices, each vector (FM, DAB +, CATV, IPTV, Webstream etc.) can be delayed so that their audio arrives at the listener at the same time.
The USV Monitoring Circuit controls constantly the USV output voltage. In the case the output voltage breaks down (due to a defect or bad batteries) a controlled switchover will be induced. With this device transmission interruptions can be prevented.
In the event of a temperature rise in the technical room, act quickly and efficiently thanks to the temperature monitoring system with SMS notification and visual alarm.
Three sensors monitor the studio signal. In case of failure, an emergency program is started or switched to a redundant audio supply.
